Hi All
I would like to ask a basic question on materials. We are a pipe line operating company. Our gas pipe line material is API X52 with a maximum operating pressure of 7332 Mpa. In general one can hydrotest pipe lines to 100% or even 110%SMYS.I have made to understand that 100% SMYS is the yield point of the materil.If that the case how can you hydro test to 100% or above of the given SMYS?
